Reducing the number of API calls made by your site and mobile application is a surefire way for every business to reduce cost, reduce code complexity, and improve page load performance.
You can now retrieve data representing the number of questions and answers for a given product, from the same endpoint used for gathering statistics for ratings and reviews.
For example, you could now make just one call to the Statistics API Endpoint to gather the data required for displaying an inline rating summary (star rating, number of reviews) which also includes a summary for questions and answers (number of questions and answers) for a given product. This used to typically consist of three calls to three different endpoints.
